chines, of which the followinglis a specification. i

- call T actuated means for renderin the movements of the printing keysinoperative to actuate the printing instrumentalities, as for instance,when the carriage reaches the end of a line, thus preventing thepilingup of the characters at the end of a line.

The main object of my invention, generally stated, is to providecomparatively simpleand efficient mechanism of the character specified.

Tothe above and other ends which will hereinafter appear, my inventionconsists in the features of construction, arrangements of parts andcombinations of devices to be hereinafter described and particularlypointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicatecorresponding parts in the various views, Figure l is a fragmentary,central, vertical, fore and aft sectional view of one form oftypewriting machine embodying my invention, suificient parts only of themachine being shown to illustrate my invention in its embodimenttherein. Fig. 2 is a fragmentary, detail, side elevation of some of theparts shown in Fig. 1, the parts being represented in differentpositions from those in which the corresponding parts are shown inFig. 1. Fig. 3 is a fragmentary, front elevation of the machine withparts in section. Fig. t is a fragmentary transverse sectional view ofone of the contact devices for the controlsame in the carriage in aconventional manner.

\The frame of the machine comprises a base 1, corner posts 2 and a topplate 3. The top plate supports fixed oppositely grooved guide rails 45which receive antifricti'onballs or rollers 5, and these rollers arelikevi' isereceived in oppositely grooved rails 6. The rails 6constitute the forward and rear cross bars of a carriage '7. Thecarriage is thus mounted for movement from side to side of the machineover the top plate. Acylindrical platen 8 is supported in the carriagein any suitable manner. Arms 9 are pivoted at 10 to lugs 11 whichproject upwardly from the rear cross bar of the carriage, near the endsthereof. These arms support a feed rack 12 which meshes with a feedpinion 13. The feed pinion is fixed to the forward end of a shaft 14:mount ed to turn in a bearing 15, secured to the top plate of themachine. The rear end of the shaft 14 extends beyond the bearing 15 andhas a doubleescapement wheel 16 secured thereto. The escapementwheel maybe of the character employed in the No. 10 Remington machine, a singlefeed dog 17 cooperating therewith. The feed dog is carried by a. dogrocker 1 8, pivoted at 19 to rearwardly extending bracketarms 20 carriedby a bracket plate 21, secured to and depending from the top plate. Aforwardly projecting arm 29. projects from the dog rocker and has adownwardly extending link 23 connected therewith. The lower end of thislink is connected to a rearwardly extending crank arm 24 which projectsfrom a rock shaft 25 mounted at its ends in suitable bearings in thebase of the machine. Therock shaft also has, near the ends thereof,rearwardly projecting crank arms 26 connected to depending links 27which support a universal bar 28, the latter extending beneath theseries of key levers 29. A contractile spring 30 is connected at one endto a pin 31 projecting from the dog rocker, whereas the opposite end ofsaid spring is connected to an arm 32 secured to the bracket plate 21.This spring returns the dog rocker and universal bar to normal positionshown in Fig. 1. It will be understood that each down and up movement ofthe uni- "applied thereto by the usual, spring drum (not shown).

The key levers 29 are fulcrumed on a fulkey 36. Each key lever has anupwardly extending projection 37 with a vertically' disposed slot 38therein. The lower end of each slot is extended rearwardly to form anoff-set engaging notch 39. upwardlyextending actuating link 40cotiperates with each key lever and is provided at its lower end with anengaging device or pin 41 received .in the slot" 38 of theasspciated keyQ lever 29. Each pin extends between arms formed by the lowerbifurcatedend of its associated actuating link. Each pin 41, as [will beseenfrom a comparison of Figs. 1 "and 2, is adapted to move in theverticalslot i Z 01 the'associated key lever, or to be received in theengaging notchor opening 39'ain the .leVer. The upper end of eachactuating link I} --is pivotally connected to a sub-lever 42 pivoted at43 to. a hanger 44. The rear end of each sub-lever is connected to alink 45 which in turn is connected at its rear end to a type bar 46.Each type bar is pivoted at 47 to a hanger 48 secured to a type barsegment 49 and the type bars are segmentally arranged on the segment tomove upwardly and rearwardly to strike against the front face of theplaten 8. Each of the actuating links 40 extends through an opening 50in a controlling device or member comprising a horizontally disposedflange or bar 51 which extends transversely of, the machine across andabove the system of key levers. An upwardly extending flange 52 isformed as a 1 part of the bar 51 and is provided with for- 5 wardlyextending e'ars'53 at'the ends there-i of; -These ears are pivoted at 54to bracket arms 55, secured to the-base of the machine. ,In this mannerthe bar 5152 is pivotally asupported for movement fromfthe positionshown in Fig.- 1 to that indicated in Fig. 2,

or vice versa. The openings 50 in the bar or controlling member are suchas to afford a free longitudinal movement of the actuating 1 linksduringthe operation of the type bars under control of the finger keys.When,

' however; the controlling bar is moved from the position shown in Fig.1 to that indicated in Fig. 2, it is effective to swing the links aroundtheir upper pivoted ends, thus moving the lower ends of the entire setof actuating links transversely and toward the front of-the machine, tocarry the pins. 41

- thereon ou't of the engaging notches 39 and into the lower ends of theslots 38. It'will 6 v be understood-that at this time an actuation ofany of the fingerkeys 36 is ineffective to transmit movement to the.associated actuating link 40 and the type bar controlled thereby;the-pin 41' playing freely in the vslot 38. The effect therefore ofmoving the bar 5152 from the position shown in-Fig; 1 to that indicatedin Fig. 2 is to disconnect the printing keys 36 from the type bars or toaflord a lost motion between the parts; whereas a movement of the bar inthe opposite direction or toward the rear of the machine is efi'ect-iveto seat the pins 41 on the various actuating links in' the engagingnotches 39 in the key levers, thus reestablishing operative and positiveconnection between the finger keys and the type bars;

The bar 51-52 is automatically controlled by the travel of the carriage,so that when the carriage reaches the end of a line for instance, saidbar will be moved to theposition shown in Fig.2, thereby automaticallydisconnecting the printing keys from the printing instrumentalities ortype bars.- Any suit-able means may be employed etc 1 bring about theautomatic actuation ofhlthe bar 51-52. In the present instance I haveshown means similar to the line lock devices employed in the No. 10Remington machine,

for'ettecting an actuation of the bar. Thus an adjustable stop orcontact device 56 is supported-on the front cross bar of the carriagefor adjustmentthereon in the direction of-the travel of the carriage.This contact device is adapted to cooperate with an up- .4 .Wardlyextending contact device "57 mounted on the frame of the machine. Froman inspection of 'Fig. 4 it will be. observed that this contact device57 is fixedly mounted on a trunnion-like pivot '58 which is received inbearings 59 and 60 of a bra'cketwhich is secured by screws 61 to a frontfixed carriage rail. An expansion spring 62 is received in the bearing59 and bears against a'fixed abutment at one end and against the bottomwall of a recess in one end of the pivot 58. The pressure of this springis exerted to move the contact device ,57 axially of its pivot 58 and tothe right, Contact walls 63 co-ac't with the contact device v57' tolimit its movement to the left after a movementhas been transmittedthereto corresponding to a single letter space movement of the carriage.The contact device 57 is maintained normally in engagement with contactwalls 64 by the pressure of the spring 62, said Walls limiting themovement of the device 57 .to the right. It will be understood that thecontact device 57 is mounted for axial as well as for pivotal movementaround the pivot 58, the axial movementbeing effected in onedirectionagainstthe pressure of I the spring 62." The pivotal movementof the contact device is eflected by a finger piece 65 connecteddirectly therewith and ar ranged "at the front. of the' machine 'whereand at its lower end to an upwardly pro-' it convenient for actuation.The part 57-65 is restored to normal position around its pivot 58 by thespring 62. A depending portion 66 is formed on the contact device 57 andthis depending portion is slottedat 67 for the reception of a bent end68 of a connectin link or rod 69. The rod 69 extends to t e left and isreceived in a groove or cut-out 70 in the bottom of the forward fixedguide rail. The left-hand end of" this rod is connected to an angularlever 71, pivoted on a shouldered 'pivot screw 7 2, carried by theleft-hand forward bracket which supports the forward guide rail 4. Adepending link 73' is connected at its upper end to the angular or bellcrank, lever 71,

jecting ear 74 formed on ,/the flange 51 of thercontrolling bar ormember 51-7-52 at one end thereof. It will be understood that thecarriage i its mov nent from right" to left is effective to bring t'econtact device 56 into engage ment with the contact device 57, movingthe latter to the left. This movement of the contact device, 57 takesplace after the operator has been notified' by the usual alarmmechanisnynot shown, of the approach of the'carriage to the end of theline. The power of the carriage spring in the movement of the carriagefromv right to left is effective to overcome the power of the spring 62and to move the contact device 57 to the left with 'the carriage adistance corresponding to a letter space movement of the carriage. Thismovement of the contact device 57 is effective to move the link 69longitudinally, transmitting a downward movement to the link 7 3,through. the inter.- posed bell crank 71. The downward movement of thelink 7 3 is effective to move the controlling member 51-52 from theposition shown in Fig. 1 to that indicated in Fig. 2, thus throwing thepins 41 on the set of actuating links out of the engaging notches-39 andinto the slots 38. A depres-- sion of a finger key at this. time merelyresults in depressing the associated key lever without transmittingmovement to the printinginstrumentalities, thepin 41 on the associatedlink playing freely in the .slot 38. The key lever moving downindependently of the associated type bar 46 and its actuatin connections45, 42 and 40 will move with a ghtne'ss of touch which will at once warnthe operator that the parts are disconnected and that the type barscannot be operated.

I preferably employ a fixed stop; rod 91 covered with a cushion 92against which the disconnected key levers are adapted to strike to limit,their downward movements at about the termination of the lost :motionbetween. the key levers and the links 40 .as shown in Fig. 2.

tends transversely beneaththe key levers This stop rod e'x-.

held against further movement by the cooperation of the contact devicesor stops 56 and 57. The stops can move no farther to the left and theyhold the carriage in the position at which it has been arrested. Shouldthe operator desire to reestablish connection between the finger keysand the printing instrumentalities, to insert a hyphen or complete aword, it is merely necessary to depress the finger piece 65, thus movingthe contact device 57 out of the path of the stops 56. This clearance ofthe stops enables the spring 62 to move the stop or contact device 57 tothe right, thus enabling the parts to be restored to the normalpositions indicated in- Fig. 1, and reestablishing operative connectionbetween the finger keys and the printing instrumentalities. The operatoris then at liberty to continue the writ ing.

I It will be understood that in the use of my invention no shock orstrain is exerted on line lock mechanism resisting the pressure exertedby the operator on the finger keys.

A final contact devlce '7 5, a margin stop 7 6 and a'final margin stop77 are constructed and arranged in the same manner as in the No. 10Remington machine, and cooperate with the contact device 57 in the samemanner as the corresponding parts in said machine. Further descriptionof the operation of these parts is deemed unnecessary for the purpose ofmy present invention.

It will be understood that an adjustment. of the stop 56 regulates thelength of a line; I

that the intermediate actuating connections between the finger keys andtype bars are such that they may be automatically broken or renderedinefiective to transmit movement from the finger keys to the type bars;that in the present instance the eflectiv'e connection is broken by theproduction of a lost motion connection due to the pins ll working in theslots 38, and that the finger piece" 65 and the parts controlled therebyconstitute hand controlled means operable at will to reestablishoperative connection between the finger keys and printinginstrumentalities,and thereby render the finger keys operative on theprinting instrumentalities.
